Heat the olive oil in a large, deep frypan over medium heat. Add the onion, chorizo and bacon and cook, stirring for 5-6 minutes until onion is soft and bacon is starting to crisp. Add the rice, stirring to coat in the mixture. Add the tomato paste, capsicum, tomato, garlic and paprika, then cook, stirring, for 2-3 minutes. Add saffron, chicken stock and wine, then bring to the boil. Simmer gently uncovered, stirring occasionally, for 15 minutes or until the liquid is evaporated and the rice is just cooked.
